摘　　要：混凝控制指标的确定和涡漩理论的作用是混凝动力学中最为关注的问题,本文以往复隔板絮凝池的改造为例,对最佳水力条件下混凝控制指标的合理选用进行了讨论,并在此基础上对池中水流涡漩运动进行了研究,得出适宜的速度梯度G值有利于形成更多更小的微涡漩,可使颗粒有效碰撞次数增加,有效地提高混凝效果。The determination of coagulative control index and the effect of the eddy theory are the most attention problems in the coagulation dynamics.How to select rational G and Gt was discussed under the optimum hydraulic condition.On the basis of this,the eddy motion of flow in the reciprocating baffled flocculent tank was studied.The results showed that the rational coagulative control index is favorable to form even more and smaller infinitesimal eddy,the effective collision is increased and coagulative effect is improved apparently.
